Hematite is an important ironcontaining mineral [4], and is also the main raw material for ironmaking. Hematite is embedded with extremely fine particle size in hematite ore, and is closely symbiotic with gangues such as quartz, chlorite and amphibole [5]. To achieve the monomer dissociation of useful minerals, fine grinding is required.

Grinding tests were conducted on an oxidized coppercobalt ore using a pearshaped ball mill. Twelve monosized ore fractions were prepared and wet ground batchwise. The mill was run for to 30 min intervals. The shortest interval provided data more closely related to the breakage function (B) because less secondary breakage was hypothesized.
